SYRINGE Filed July 2 1943 2 Sheets-Sheet 1 Inventor Pangkz'm Patented Oct. 2, 1945 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to new and useful im provements in syringes and more particularly to a vaginal douche syringe.

The present invention is an improvement on the patent to J. W. Brunette, No. 1,751,507, issued March 25, 1930.

The principal object of the present invention is to provide a syringe having drain-oil means and a liquid escape guard, wherein the guard functions much more satisfactorily than the corresponding feature of the above-named patent.

Another important object of the invention is to provide a syringe of the character stated which can be used with more comfort and effectiveness than devices heretofore known.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a side elevational view of the syringe.

Figure 2 is a top plan view.

Figure 3 is a vertical sectional view.

Figure 4 is a section on the line 4-4 of Figure 1.

Figure 5 is a section on the line 5-5 of Figure 1.

Figure 6 is a fragmentary vertical sectional view showing a modified form of the invention.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1 that numeral 5 denotes a circular body which serves as a shield or guard against the escape of douche fluid. This may be of hard rubber, and has imbedded therein the flanged end 6 of a hollow fitting 1, which at its lower end, as shown in Figure 3, has a hose attachable nipple 8.

A tube 9 extends upwardly in the fitting l and spacially with respect to the side thereof, and at its lower end has a laterally disposed exten- 1 sion merging with the side wall of the fitting I,

and outwardly from this portion of the side wall extends a hose attachable nipple l0.

Projecting upwardly from the guard body 5 is an elongated nozzle ll having a gradually tapering head 12 in which discharge openings l3 are located. Additional discharge openings I 4 are located just short of the head I2, while at the point of the nozzle H where it connects with the guard body 5, the nozzle bulges as at l5 and has therein formed slots I6, communicating the outside of the nozzle II with the interior of the bulged portion l5 as well as with the interior of the fitting 1.

It can here be seen that a passageway I1 is formed longitudinally in the nozzle H and this passageway terminates at a seat I8 at the lower portion of the nozzle and with it engages the beveled upper end portion of the tube 9.

A trough I9 is formed in the guard body 5 immediately adjacent the slotted portion of the bulge l5 and outwardly from this trough the guard body gradually slopes on a concave to its periphery as denoted by reference character 20.

It can now be seen that douching liquid enters the nipple H] by way of a hose (not shown),

flows through the tube 9 and nozzle II, and after performing its cleansing operation flows back along the outside of the nozzle H and is caught by the trough l9 and to an extent guided by the concaved formation of the top side of the guard body 5. The fluid enters the fitting 1 by way of the slots I6 and passes through a drain tube attached to the nipple 8.

Figure 6 shows a slightly modified form of the invention in that the nozzle Ila is constructed of hard rubber or like material, this nozzle having a bulged portion l5a, the slots Ilia, and a guard body 5a having a trough I9a. In carrying out this form of the invention, the guard body 5a has a short neck 22 flanged as at 23. A fitting 1a is provided and, accommodates a tube 9a and a nipple Illa and this fitting la is flanged at its upper portion as at 24. A suitable annular clip or detent 25 is used to bridge the fianges 23, 24, and between these flanged portions of the two sections a suitable gasket 26 may be interposed.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described claimed as new is:

In a device of the character described, an elongated, hollow nozzle provided with a head having discharge openings therein, an enlarged portion adjacent the base of said nozzle having a pluthe invention, what is 'rality of slots therein, a liquid escape guard body having a groove therein adjacent said enlarged portion of said nozzle, a relatively rigid fitting comprised of a pair of concentric tubular por-- tions secured to the guard body, said inner tubu- -lar portion extending beyond said guard body
